> The qpid java broker does not deal effectively with slow consumers. This is a
> combination of two issues: a MINA issue and a lack of support in qpid itself.
> The MINA issue is similar to the "fast producer" issue. In this case, the
> data is stored in the MINA session queues, and does not appear in the queue
> counts which makes it very difficult for users to track down. Each MINA
> session event queue needs to be a bounded list.
> The broker also needs enhancement to offer at least two options when a queue
> builds up:
> 1) throttle the publisher. This is likely to be something that is desirable
> for "public" queues.
> 2) disconnect the slow consumer. This will be used when dealing with private
> queues - typically bound to a topic exchange.
